STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 311,209, dated January27, 1885.

Application filed January 29, 1883. (N0 model.)

To all whom it may concern.-

Be it known that we, DUDLEY D. SPRAGUE, a resident of California, in thecounty of Moniteau, CHARLES D. SPRAGUE, a resident of Ohilhowee, in thecounty of Johnson, and PEARLEY J. SPRAGUE, a resident of Higbee, in thecounty of Randolph, State of Missouri, all citizens of the UnitedStates, have invented certain new and useful Improvements in Straw-Stackers for ThrashingMachines; and we do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

Figure 1 of the drawings is a View of our improved stacker and a portionof one side of the machine, and Fig. 2 is a view of the opposite side.Fig. 3 is a bottom view of the base of the stacker. Fig. 4. is across-sectional view, and Fig. 5 is a detail view, showing the arm foradjusting the intermediate carrierframe, to which the elevator-frame issecured. Fig. 6 is a side elevation showing the stacker folded fortransportation.

This invention has relation to straw-stackers for thrashing-machines;and it consists in the construction and novel arrangement of devices, aswill be hereinafter fully described, and particularly pointed out in theclaims appended.

In the accompanying drawings, the letter A represents the main frame ofthe separator, and B the sills thereof.

O indicates the supporting-frame or base of the stacker, which isattached to the sills 13,01: other portion of the frame A, in rear, bystraphinges or other flexible connections, as indicated at a. This frame0 is supported at its outer end by a prop or props, I), made adjustable,in order to steady the frame 0 on uneven ground. By means ofa guy-chainor guychains, 0, connected to the outer end of the base or frame 0 andhooked to the main frame A, the stacker is supported when the machine ismoving in changing its location.

On the frame 0 is secured a circular track,

D, on which rests the pivoted frame E, which is held in position bymeans of the vertical center-pin or pivot-bolt F, which passes through abearing of the frame E and is secured to the frame 0, so that the frameE can be turned horizontally.

At the ends of the upper portion of the frame E are arranged in suitablebearings, as at b, the transverse shafts (Z d of the intermediatecarrier, \V, which is designed tore-M ceive the straw from the separatorand deliver it to the long carrier or elevator K, the frame of which ispivoted to the outer end of the frame E. The elevator-frame istransversely divided into parts hinged together. Suitable bolts securethe parts in working position, as shown.

On the under side of the frame 0, and in bearings e 6 thereof, is thedriving-shaft G,

which carries on its outer end the first driving wheel or pulley, f, andon its inner end a bevel-pinion, c.

On the under side of the pivoted frame,and in bearings 9 thereof, is thesecond drivingshaft, H, which carries on its inner end the bevel-pinione, and on its outer end a sprocket-wheel, I, which engages a chain belt,h,

which also engages the sprocket-wheels j t l am. By means of these orsubstantially similar gearing motion is communicated to the shaft d ofthe intermediate or donkey carrier, and to the shaft J of the maincarrier, which is pivoted in bearings of the frame E, as indicated atf.The shafts G and H extend radially from the pivotal center of the frame0, and engage by their respective pinions, e e", an idle-wheel, p, onthe pivot-bolt F. The idle-wheel p is made larger than the pinions e 6,so that the traveling pinion 0 will not come in contact with thestationary pinion e of the shaft G when the pivoted frame is turned inlateral position. The sprocket-wheels j and m are connected to a take-uplever, T, which is secured to the frame E by means of a pin or bolt, is,passing through said lever, and through the idle-wheel m. The wheel j ispivoted on the arm of the lever, and the chain belt passes over it. Thislever is used for taking up slack in the chain belt when necessary.

K represents the elevator-frame,which rests in pivotal bearings at theouter end of the pivoted frame E, somewhat below and at a suitabledistance from the discharge end of the intermediate carrier, NV. Theouter portion of the elevator-frame K is provided with a bail or guys,as indicated at s, to which is connected a centrallyarranged rope orchain, M, which extends over the pulley N to the governing-Windlass O,and serves to support the elevator-frame in inclined position.

P indicates a supporting-frame or derrick, made of wood or iron, inangular form, having its lower ends connected to the top of theseparator, near its rear end, by means of hinges or pivotal connections,as indicated at t, in order to allow the derrick to be folded down onthe top of the separator. Connected to the top of the derrick is a guychain or rope, Q, which extends forward and downward, and is connectedto the top of the separator. This guy serves to prevent the derrick,when in raised position, from becoming too much inclined, holding it inposition with its upper end directly over the pivotal center of theframe E.

The pulley N, over which the supportingrope M passes, is hung from theupper end of the derrick P by a short chain or swivel con nection, asindicated at Z, so that the pulley will readily turn in adjusting itselfto the different positions of the rope M when the elevator-frame'and itspivoted frame are moved toward one side or the other. The lateraladjustment or turning of the pivoted frame can therefore be made whilethe machine is in operation without having recourse to special adjustingdevices.

Attached to the discharge end of the upper pan or separating-floor ofthe separator are the lateral inwardly-inclined or contractingguide-boards or side pieces, X,which serve to compress or condense thestraw as it is discharged from the machine upon the intermediate carrierof the stacker.

Z represents the controlling arm of the stacker,whicl1 is secured to thepivoted frame E, and extends outward over and beyond the track of theframe 0 sufficiently to form a handle. The circular track is providedwith an outer ratchet or series of notches, as indicated at r, and thearm Z with a ratchet-latch, y, adapted to engage the ratchet. The innerend of the ratchet-latch y passes through a bearing at y on the arm Z,and its outer end is pivoted toarocking hand-hold, z, havingaspring, s,between said hand-hold and the lever, which forces the hand-hold outwardand the latch y into engagement with the ratchet. By means of thisdevice the pivoted and elevator frames can be turned and held in anydesired position.

machine and swinging elevator, to follow the lateral swing of theelevator and transfer the straw thereto.

combination of a supporting-frame, a carrierframe pivoted to turn on thesupporting-frame, and an elevator-frame hinged to the carrierframe toturn therewith, as set forth. 3. In astacker, the combination of apivoted horizontallymovable frame, an endless carrier in said frame, andan elevator-frame having an endless carrier and hinged to the movableframe, as set forth.

4. The combination, with the main frame of a thrashing-machine, of thepivoted horizontally-movable intermediate frame, a carrier,and avertical]y-adjustable elevator-frame connected to the outer end ofthe'intermediate frame.
